I read "Plenty in Life is Free" a year ago and really loved it. I think the thing that stood out for me was that she considered the spiritual side of dog training, not just the science. It is so true that we learn so much about dogs when we have one with behavior problems, and we see other people and their dogs completely differently. Kathy Sdao realized that the advice she had been giving her clients was wrong when she finally got a dog of her own with some serious issues. I need to read the book again!
